The Stand Mixer Speed Control Plate controls the speed of the stand mixer motor. The speed control plate is part of the speed control system. To access the part, remove all attachments and the bowl of the mixer. Then remove the back cover of the mixer and the screws from the trim band. Remove the wires from the seal of the mixer in order to take the spring off of the speed control plate. Make sure you hook the spring with a needle nose pliers securely to remove. Disconnect the wires from the phase control board. You'll then be able to remove the upper two screws holding in the old speed control plate. Note: These upper two screws are where you adjust the speed of your mixer. Make sure you measure them from the back of their post to the back of the speed control plate at 3/8". This part is designed to be used with select Whirlpool® and KitchenAid® stand mixers; check to see if your model is compatible. Replacing this part will require basic hand tools, some disassembly of the stand mixer and novice repair experience. You must unplug the appliance before installing this part.
